War is a necessary evil
War, as i see it, is optional.
But we, as human beings, don't believe it is. That is ALL that makes it "necessary". Because for it to be optional, you actually need the all pople involved to decide not to fight.
And they don't do it, because, again, they think it is actually necessary to fight. For whatever reason.
It is, as i see it, a really, really stupid cycle.
